A friend of mine compared it to picking a Protestant church. We all use the same Bible, but the leadership and members make all the difference. Even among a particular denomination, you will see variations good and bad.
The tutor is expected to discuss the upcoming assignments at some level and go over homework. Their ability to deal with the upcoming assignments will depend on their expertise. Some will bring their experience and background in IEW and Andrew Kern's materials in, and some will rely pretty much on what CC provides. Some will teach the different types of writing and give written feedback on the assignments, and some will read from the guide and put a checkmark on the assignment to show that they've read it. Some will offer extra tutoring sessions, and some will not. In class there may be more or less involvement to ensure that errors are corrected on assignments.
As I posted on another thread, I've decided that the key is my involvement. I would say that it is much more important than most parents appreciate. This year we did Challenge and online classes, and the line between parent and teacher was different. In Challenge, I provide the detailed expectations and grade a fair amount of the work. In online classes, the expectations are given up front in the form of a detailed rubric, quiz, or other evaluation tool, and in most cases the instructor grades it or I grade it based on their detailed guidance and email the instructor the score. Both are valid approaches, but are not the same by any means.
In our experience, Challenge has been especially good for subjects where group involvement made the difference and where the tutor was themselves an inspiring individual. Where I've been disappointed, one or the other of those issues was at the forefront. Next year our plans involve a mixture of Challenge, online, and mom-taught for different kids. And no, I never became a Director. God led to other areas.
